Anti-XYLT1 antibodies are used in the immunodetection of the protein xylosyltransferase 1. In humans, the canonical protein has a reported length of 959 amino acid residues and a mass of 107.6 kDa. Its subcellular localization is in the Golgi and is secreted. It is widely expressed across many tissue types. A member of the Glycosyltransferase 14 protein family, XYLT1 is known to catalyze the first step in the biosynthesis of chondroitin sulfate and dermatan sulfate proteoglycans, such as DCN. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include peptide O-xylosyltransferase 1, xylosyltransferase I, xylosyltransferase iota, and beta-D-xylosyltransferase 1. XYLT1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some XYLT1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
